Disk-Level Behavioral Malware Detection (2009)

Nathanael R. Paul, R. Paul, Sudhanva Gurumurthi, Nina Mishra, ...

We present a new malware detection method that takes advantage of the processing power now available on disk drives. Our method uses the disk processor to monitor disk requests and identifies...

Intra-Disk Parallelism: An Idea Whose Time Has Come (2009)

Sriram Sankar, Sudhanva Gurumurthi, Mircea R. Stan

Server storage systems use a large number of disks to achieve high performance, thereby consuming a significant amount of power. In this paper, we propose to significantly reduce the power consumed...

Sensitivity-Based Optimization of Disk Architecture (2009)

Sriram Sankar, Yan Zhang, Sudhanva Gurumurthi, Mircea R. Stan, Senior Member

Abstract—Many applications, especially those that run on servers, are I/O intensive and therefore require high-performance storage systems. These high-end storage systems consume a large amount of...

Thermal Issues in Disk Drive Design: Challenges and Possible Solutions (2008)

Sudhanva Gurumurthi

The importance of pushing the performance envelope of disk drives continues to grow in the enterprise storage market. One of the most fundamental factors impacting disk drive design is heat...

SYSTEMS AS DEMANDS FOR HIGHER DATA TRANSFER RATES MOUNT, TEMPERATURE IS JOINING BANDWIDTH AND LATENCY AS A KEY CONSIDERATION IN STORAGE SYSTEM DESIGN. THE STEAM SIMULATOR LETS USERS ABSTRACT THE DETAILS OF LOW-LEVEL RECORDING PHYSICS AND HEAT TRANSFER PHE (2008)

Sudhanva Gurumurthi, Youngjae Kim

Computing today is highly data-driven. Many applications, especially in the business and scientific domains, must move massive amounts of data between the computing nodes and the storage system at...

RPM Rotations Per Minute (2008)

Sudhanva Gurumurthi

Storage has become ubiquitous. Disk drives are commonplace in most laptops and desktops. In addition, they are used in large numbers in high-end server systems. Storage devices have also proliferated...

A Benchmark Suite for Unstructured Data Processing (2008)

Clinton Wills Smullen, Iv Shahrukh, Rohinton Tarapore, Sudhanva Gurumurthi

A large fraction of the data that will stored and accessed in future systems is expected to be unstructured, in the form of images, audio files, etc. Therefore, it is very important to design future...

Towards Disk-Level Malware Detection (2008)

Nathanael Paul, Sudhanva Gurumurthi, David Evans

Disk drive capabilities and processing power are steadily increasing, and this power gives us the possibility of using disks as data processing devices rather than merely for data transfers. In the...

Thermal Attacks on Storage Systems (2008)

Nathanael Paul, Sudhanva Gurumurthi, David Evans

Disk drives are a performance bottleneck for data-intensive applications. Drive manufacturers have continued to increase the rotational speeds to meet performance requirements, but the faster drives...

Intra-Disk Parallelism: An Idea Whose Time Has Come (2008)

Sriram Sankar, Sudhanva Gurumurthi, Mircea R. Stan

Power is a big problem in data centers and a significant fraction of this power is consumed by the storage system. Server storage systems use a large number of disks to achieve high performance,...
